Version Control With Subversion Source

In the help for "svn log", do not allow multiple local paths because such
usage does not work properly, and specify the default revision range because
it differs between URL and local usage and has confused people.

* doc/book/book/ch08.xml
* subversion/clients/cmdline/main.c
* subversion/tests/clients/cmdline/getopt_tests_data/svn_help_log_switch_stdout
In the help for "svn log", do not allow multiple local paths, and specify
the default revision range.

* doc/book/book/appb.xml

Remove the python bindings requirement from the chapter on cvs2svn.py.
It was removed from cvs2svn.py a long time ago.

Add 'pd' alias for propdel command. Patch mostly by Christian Sauer
(christian@...).

* subversion/clients/cmdline/main.c: Added "pd" as a shorthand for
propdel so it is consistent with the shorthands for propedit,
propget, proplist, propset.

* doc/book/book/ch08.xml: Update docs

Widen the file size column in "svn list" output, because sizes over 8 digits
are becoming common. Update the examples in the book.

* subversion/clients/cmdline/ls-cmd.c (print_dirents)
Widen the file size field to allow 10 digits before breaking alignment.
[From Martin Maurer.]

* doc/book/book/ch03.xml
* doc/book/book/ch08.xml
Update the examples of "svn list" output to reflect this change and the
recent removal of the first ("has properties") column.

Remove the "has properties" field from the output of "svn list", because it
was not very useful in general - e.g. if "svn:eol-style" is set for all files,
then this field is always true and thus uninteresting.

* subversion/clients/cmdline/ls-cmd.c (print_dirents)
Remove the 'P' field.

* subversion/clients/cmdline/main.c (svn_cl__cmd_table)
* doc/book/book/ch08.xml
Remove mention of the 'P' field from the help for "snv list".

Expand and correct the help for "svn list".

* doc/book/book/ch08.xml
* subversion/clients/cmdline/main.c (svn_cl__cmd_table)
Re-write the entry for "svn list".

Fix the description of "svn copy": it only modifies the repository or WC of
the destination, not of the source.

* subversion/include/svn_client.h
(svn_client_copy) Fix doc string.

* doc/book/book/ch08.xml
Fix "Changes" and "Accesses repository" subsections of "svn copy".

* doc/book/book/ch03.xml
Explain that saving an empty log message is similar to not saving
one at all.

Book fixes from Mason Thomas <mason@...>.

* doc/book/book/ch03.xml: Update sections for consistency.

* doc/book/book/ch05.xml:
Fix some sample usages of the 'svnadmin dump' commandline. Patch
by Chris Foote <cfoote@...> (tweaked an itty bitty bit by C-Mike).
